Default mm210: going beyond the door chart

This question pertains to the door chart on the 210 welder. Most of the time I find that I like going 1 or 2 settings higher than the door chart.
I'm currently working on a project involving 5 inch square tubing 1/4 thick welded to 10 inch wide C channel also 1/4 thick. Large pieces, that take a lot of heat. I was running 1 setting higher, at the setting for 3/8 thick steel on the door chart which is 5 and wfs =70, for .030 wire and c25 gas. I hesitated to go beyond the door chart because I didn't know if I'd start going into a bad version of globular transfer or anything like that. I got penetration at the 5/70 settings, and it seemed ok. This morning however, with temperatures hovering around 35 degrees in the garage, I went beyond the door chart to see what would happen. Turns out I really like 6 and wfs=80 for this thickness steel. It was sweet. I'm sure the 210 was fine, not worried about that, but overall should I have any concerns going beyond the end of the door chart? No more columns! Could I be beyond the capability of .030 wire? What is the capacity of .030 wire? Am I crossing over into globular transfer, or anything? What concerns should I have about doing this? If it's all ok to do, then why does the door chart not show another column or two? I know the miller door charts are conservative, but how far can I go beyond the door chart before I hit another limitation? Let's say I was doing 3/8 steel with .030 wire, what settings would you use? I'd say at least 6 and 80, maybe even try 7 and 90?

Bob, don't worry about it. You aren't going to hurt anything. I regularly go one notch above the DC or more. You shouldn't be in glob on tap 6. Glob usually starts with tap 7/50-60....for stable globular transfer anyway. Being in glob isn't necessarily a bad thing. If you haven't tried it, do so. Set it at 7/80 and have fun...mind the duty cycle, though. As far as the capacity of the wire, you may be near the end of its usefulness, but not enough to worry about. The wire will be fine.

If you haven't already, try some settings above the DC and see what you like the best and take notes. Most of the time, experienced weldors will like hotter settings. Experiment with everything and note the changeover to globular and learn how to use it. It can be your friend.

I am always at least a setting for thickness above the charts.

Seems like the DC on most machines are on the cold side.

Don,..... you convince Sberry to swing by the "Pit" yet?

Sberry,..... if you don't your missing out!

someone sounds paranoid. the door chart is ONLY a suggestion to get someone started it the right area of the ballpark. I dont ever look at the door chart. before I start welding I use a peice of scrap of the same thickness and adjust accordling to the scrap. Then when I get a setting that works very well, I write it down on a notebook I keep in my welder. Now I hardly ever have to fine tune my welder, I just look at my notebook and start welding from there. Works every time for a perfect weld.

As for glob transfer dont worry about that either. You will know it if you get in that trans mode. The bead is very large and drops very slow and not as many as with short arc. With the machine maxed out you are also maxing out the little 030 ire you are running. but I dont think you would be hurting anything, the wire just cant cary as much volts/amps compared to 035 wire.

I just suggest stop worrying about it and just weld.

Kind of like reloading. Nobody goes by the book, it's just a good starting point.

I agree... Dont' worry about it and burn. Burn on scrap to get it adjusted right if you need to. Play around with it and see what the results are. Adjust up or down if ya' need to... You'll find a combination that works better for your style of welding than what the door "suggests".

Kind of sounds like '70s porn though... "Beyond the Blue Door"

Below 1/8, I don't have a problem with the DC. It is good enough. I just get hotter above 3/16. My power is kinda hot, so that may be why. The machine is set at 230vac and I have a good and steady 244vac.



Bob, even if the .030 is at the top of the spec, don't change to .035 unless you just want to. The MM210 is optimized for .030. It will run .035 just fine, but it will rock on .030.

I agree the machine is optimized for .030"
I've found that the door chart is just a guidline.
When I find a sweet setting, I write it on the door with a magic marker.
